REGINALD FOWLER REED, OF TORONTO, ONTARIO, CANADA.

WATER-COIL.

To all 107mm it may conce/m Be it known that L REGINALD FowLnn linnn, of the city of Toronto, county of York, Province of Ontario, Canada, a subject of the King of Great Britain, have invented certain new and useful Improvements in TYJilatcr-Coils, of which the following is a speciiication.

,My invention relates to improvements in water coils, and the principal object of my invention .is to construct water coils in which water is to be heated or steam generated, so that the condensation collecting thereon will be drained olf without any danger of the same extinguishing any portion of the flame of the burner underneath the same, the burner-rings of which must be placed in a particular position. And another object of my invention, in its preferred form, is to provide means for binding the convolutions of the water coil in position, and so construct the same that the condensation collecting thereon will be caused to accumulate at certain points so that itmay be disposed of without coming in contact with the burner.

Another object of my invention is to inclose the water coil, as well as the burner thereunder, in a casing, the removable cover or top of which is constructed so as to provide plenty of room above the water coil so as to insure proper air circulation to facilitate the combustion of the gas.

Further objects of my invention will be set forth in the following specification.

Generically considered, my water coil is composed of a plurality of convolutions, the contiguous ones being spaced a short distance apart and placed so that any given convolution extends a sufficient distance underneath the one immediately thereabove in order that the condensation may drain from one convolution to another, and collecton the lowcrmost convolution. Supporting or retainino` members are provided in my preferred form of construction, for the convolotions of the water coil, and the members extending below the said convolutions are so shaped as to cause any condensation accuinulating thereon to drop from given positions, as hereinafter more particularly set forth,

Figure l is a vertical central transverse section through a water coil constructed according to my preferred form of invention, and through a suitable casing therefor.

rlhis view shows in side elevation suitable supporting means for the convolutions, and a suitable gas burner, parts of which are shown in section. Fig. 2 is a plan view 0f a suitable burner, certain parts being broken away to illustrate construction. Fig. 3 is a plan view of the major portion of the upper supporting plates for my preferred form of water coil, and Fig. l is a side elevation of a section of one of the supporting bars for the under side of the sections of my said water coil.

In the drawings like characters of reference indicate corresponding parts in each figure.

It is well known by those skilled in this art, that in the ordinary water coil, the condensation will drop down upon a number of the holes of the gas burner, and so extinguish part of the flame, thus impairing the efiieiency of the water heater or steam generator. Not only is this disadvantage present, but as a further result of neglect to properly drain ofli the condensation, the supporting parts for the water coil, as well as the casing inclosing these parts, become badly rusted and consequently do not last as longas they should.

In the water coils I have constructed for use, the convolutions are spaced. about a sixteenth of an inch apart, and the external diameter of the tubing used is substantially a quarter of an inch. 0f course the space separating the said convolutions will depend upon the external diameter of the piping or tubing, as will be understood by one skilled in this art.

in my preferred form of construction, the convolutions progressively increase in dialneter from the top to the bottom of the coil, in one side of the sections, and decrease in diameter from the top to the bottom of the coil in the other side of the said sections, as will be more particularly set forth in the following specification. The gas orifices in the burner used with all forms of my water coil must essentially be positioned within the periphery of the water-coil and out of alinement with the lowerinost convolutions so that the condensation will be drained away without any possibility of the same extinguishing the burner.

My preferred construction of water-coil consists of a plurality of sections A, which are substantially shaped like an inverted V, in vertical cross section, and of course any desired number of the said sections may be used, depending upon the required capacity of the Water-heater. 1 prefer to malte my Water coil out of a length of piping, and in making it the piping is Wound around a conical-shaped body, and then When removed therefrom, it is placed over the lower supporting bars B, which are composed ot a plurality of inverted V-shaped sections C, which are in alinement. r1`he upper supporting plates D are composed ot a plurality of V-shaped sections E, the sections in each plate being in alinement. These plates D are then placed upon the coil ot piping and are pressed down upon the same, the sections E of each plate D, being positioned in the spaces F separating the sections C for the greater portion of their height. The

-outer edges G ot each section C are provided With a plurality of notches H so positioned and shaped that the convolutions ot' the said sections A are forced by the said alates D into their respective notches. Each supporting bar B is provided at each end with an extension l, and each supporting plate D is provided at each end With an extension. J. Each extension J rests upon its associated extension 1. Bolts K pass through the extensions 1 and J, and these bolts are snugly held in place by the nuts L, thus firmly clamping the plates D and the bars B together at their outer ends.

1n Fig. 3 1 shotv a plan view of the major portion ot the upper supporting plates D. These plates are preferably tour in number, and a like number ot the said bars B are used. Gf course any desired number ot the said plates and bars may be used. Through the section 2 of the Water coil 3 is a central opening e, according to my preferred form of construction, and extending down into said opening and resting against the inner convolutions ot the said section 2 are extensions 5 of the said plates D, and these extensions are connected together by a yoke piece which rests upon the yoke piece 7 connecting together the side plates 8 of certain ot the sections C ot the bars B. 9 are bolts passing through the yoke pieces 6 and 7 to secure the plates D and bars B centrally together, and 10 are nuts screwed on the ends ot the said bolts. Tie said plates D and bars B may be ot course secured together at their points ot contact by any suitable construction.

The convolutions of each ot the sections A are spaced apart so as to provide for the circulation of the heated air therebetween. The convolutions of each ot the said sections extend partly underneath the convolution immediately thereabove, and this position of the said convolutions, together With their close proximity, y rerents the formation of the condensation in the form of drops on any of the convolutions except the lower- When the condensation, for instance, collects on the under side or' the conlvelution 11, by reason of the closeness thereto of the convolutions 12 and 13, before the said condensation can be formed into a drop, it will touch the said convolutions 12 and 13 and by capillary attraction Will pass thereto and then thereover, on their inner most ones.

sides, and will come in contact With the conyolutions immediately therebeloyv. This progress of the said condensation will be continued until it collects on the lowermost convolutions 14 from whence it drops.

F rom the foregoing it Will be clear to one slilled in this art that the convolutions of the sections A are close enough together so to enable me to determine positively the positions Where the condensation Will drop from. 1 ot course may use any suitable type ot burner, and 1 shall noiv describe the construction ot the gas burner 1 prefer to use. This burner comprises a mixer 15 which opens into a distributer 16. The loyer portion 17 of the said distributer is .,ircferably integrally formed with the mixer 15, and it is provided with horizontal side anges 1S. rlhe side lianges 18 are connected together by the downward-curved ianges 19. The upper portion 2O ot said distributer is also provided with horizontal side flanges 21, and these side flanges are connected together by the upward-curved flanges 22. The said upper portion 20 is placed upon the said lower portion, and these parts are clamped together by nuts and bolts designated by the common numeral of reference 23. The said lianges 19 and 22 are clamped over the ends 2l ot the burner-rings 25 which are spaced apart. The mixed air and gas of course pass trom the distributer 16 into the said burnerrings 25, and escapes therefrom through the holes 26. Upon referring particularly to Fig. 1, it will be noticed that the burnerrings 25 are positioned substantially beneath the apex of each section A, and theretore the position of the loivermost convolutions 14C Will be, except for the outside conrolntions, directly above the spaces separating the said burner-rings. Therefore, when the condensation drops from the said convolutions 141-, it Will not come in contact With the burner-rings 25, and consequently no portion ot the burner will be extinguished. Ehe under sides of the supporting bars B are so shaped that the condensation accumulating thereon will be caused to concentrate at certain points, and these said points Will be so positioned that the condensation dropping therefrom .vill not come in contact with the burner. My preferred construction tor this purpose consists in providing the said supporting bars B With a plurality of pointed extremities 27, which are positioned so that any condensation dropping theretrom Will escape the burner-rings.

28 are a plurality of supports carried by the mixer 15 and designed to give support to the portions of the burnerrings 25 farthest removed from their supported ends 24.

In order to utilize the heated air as it escapes through the water coil 3, I preferably mount upon the top of the supporting plates D, a horizontal water coil 29.

3() are cross bars which are clamped down upon the water coil 29 to keep it in place.

8l are bolts passing through the ends of the bars 30, and these bolts pass through the extensions 32 carried by the upper portions of the plates D. 33 are nuts screwing on the said bolts.

The water, according to the construction of the water coil shown, enters into the coil through the extension 34E, and passes from this water coil into the extension 35 of the water coil 3, and the hot water or steam escapes from this water coil through the discharge pipe 36. The apexes 37 of the supporting bars l support the top-most convolutions of the water coil 3. Of course it will be understood that my particular malte of water coil may be cast or otherwise made into the desired form. Although the burnerrings ,5 are shown elliptical in cross section, they of course may be made circular or of any other desired shape.

38 is the basin of my casing. and the same is preferably provided with an annular channel 39. 1 preferably support the water coil by means of screws a() which screw through the extensions l, and the heads of these screws rest upon the floor ll of the said annular channel. By means of these screws 1 can adjust the position of the said water coil within the casing in order to keep it horizontal, and to adjust its distance from the llame of the burner.

42 is a discharge opening formed in the basin 38 through which the condensation passes.

'lhe cover or top 43 is carried by the basin 38, and this top is provided with an opening tt through which the heated air escapes. l construct the said cover so that it will extend well above the water coil so as to provi de plenty of room for the circulation of air within the said casing in order to insure proper combustion.

lt will be noticed upon referring to lfig. l that the condensation occurring on the convolutions of the water coil 29 will drop down upon the convolutions comprising` the sections A, and therefore this condensation will be arried away by the said sections after the manner already described. Of course the water coil 2S) does not form a part of my water coil 8, although l prefer to use it for the reason already set forth.

While 1 have described what lt consider to be the best embodiment of my invention, l desire it to be understood that the principles can be embodied in different forms and I de sire not to be limited beyond the requirements of the prior art, and the terms of my claims.

The lowermostconvolutions 14 form boundaries for what l may term the base of each section A, and it will be understood that the burner-rings 25 are positioned within said bases, and that the pointed extremities 27 of the supporting bars B are positioned above the spaces separating the said burner-rings 25, except for the outermost positioned of the set of said extremities, for the purpose already set forth. The middle extremities a are positioned above the opening or spaces bounded by the central burnerY ring. Although the extremities 27 and a are illustrated directly above the major portion of the distributer and mixer, it will be understood that the said distributer and mixer may be positioned so that the condensation dropping from the said extremities will not collect thereon. The parts just described have been illustrated in the positions disclosed by Fig. l for the purpose of ease of illustration. A certain amount of the condensation will drop from the convo lutions lll upon the said distributer and mixer, because these parts pass underneath the said convolutions. But the accumulation of condensation on the said parts of the burner will be very small.

The sides of the section A, illustrated in Fig. l, occupy an angle of 30 degrees to the vertical, and this is the angular' inclination of the sides of the sections in the water coils I have constructed. lVhile this angle is a convenient one, still I do not confine myself to constructing the sides of the said sections at any particular' angle provided the principle of my invention is not sacrificed.
